CYLINDER PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 230,740, dated August 3, 1880.

Application filed January 16. 1880.

To all whom it may concern:

Be it known that 1, CHARLES (J. BUTLER, of Paris, in the county of Edgar and State of Illinois, have invented a new and valuable Improvement in Stop-Gylinder Printing-Presses; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a vertical longitudinal section of my invention, taken on line m w of Fig.2. Fig. 2 is a top-plan view of the same with feed-board removed. Fig. 3 is a side view, partly in section, of the frame, cylinder, and mechanism for operating the spring-arm; Fig. 4, a side elevation of the disk and spring-arm; Fig. 5, a section of the cylinder and its connections; Fig. 6, a detail view of the plate with inclined depression.

This invention has relation to certain novel improvements in stop-cylinder printing-presses; and the object thereof'is to provide means of operating the cylinder and type-bed in this class of presses, whereby the movement of the bed is free from the rough jogging motion usually caused by the complicated arrangement of gearing heretofore employed in operating the bed of the press.

A further object of the invention is to so connect the cylinder with certain arrangement of devices that the cylinder is revolved in con- 35 junction with the bed as it is being carried forward to take an impression upon the paper, and upon the return of the bed the cylinder is caused to remain stationary without unshipping of the gear-wheel on the end of the cylinder from the rack on the bed.

The invention consists in the construction and arrangement of the several parts whereby the above results are obtained, as will be hereinafter described, and subsequently pointed out in the claims.

In the accompanying drawings, A represents the frame of a press, provided with ways or tracks a, upon which the type-bed B is supported and moves.

The cylinder 0 has connected to one of its ends a toothed wheel, b, which engages with the teeth upon a rack-bar, c, secured to the side of the type-bed.

To the frame A is connected a cog-wheel, d, the teeth of which mesh with the teeth upon a large gear-wheel, D, the same having a crank pin, 6, fitting into an elongated slot, f, of a rocker-arm, E, said rocker-arm at its upper end being formed with a segment, F. To the upper face of the segment F, and at the ends thereof, are hinged, or similarly connected, one end of suitable springs G H, the other ends of the springs being connected to the under side of the type-bed B. The springs G H bear upon the periphery or face of the segment F, and are separatedby a center flange, 9. By this arrangement of thesegment F and the springs G H the type-bed is caused to move to and fro upon the tracks a in a direct line with said tracks, thereby giving it a smooth even movement and equal bearin g upon the tracks, free from the rough jogging motion caused by gearmg.

In place of the springs G H pitmen may be substituted, connected to the segment and bed in a similar manner to the springs, which will give the same movement and draft to the typebed.

To the end of the cylinder 0 is secured a plate, I, having upon its outer face an inclined depression, h.

The gear-wheel b has secured to its face one end of a fiat spring, 43, the other end being free and having a chuck or pin, 70, which passes through an opening in the wheel I) and engages with the inclined depression h, so that when the cylinder revolves to take an impression on the sheet the chuck or pin k is caused to engage with the depression h by the action of the spring t. This revolves the cylinder in conjunction with the forward motion of the bed,and when the bed returns the recess or depression, being inclined, admits of the pin it passing out therefrom, thus leaving the cylinder in a stationary position held by a springarm, 1, which engages with a recess on the periphery of a circular disk, m, upon the opposite end of the cylinder-shaft, while the typebed returns, in readiness to make another impression without unshipping the wheel I) from the rack-bar o, the gear-wheel I) being so arranged as to revolve freely upon the cylindershaft, and is held in position against the plate I by the collar a secured to the shaft by a setscrew.

The arm 1 has a pin secured thereto, as shown at 0, which passes horizontally through the frame A and through a slotin the free end of a pivoted bar, 12, which presses against a short lever, q, by means of a spring, a, secured to the pivoted bar 19, and operating beneath said bar. The short lever q is pivoted, like the pivoted bar 19, to the inside of the frame A. The short lever q has at one end a pin, r, for engaging with a trip, 8, pivoted to the side of the type-bed B, by which arrangement the arm l is made to disengage from the notch or recess in the periphery of the disk m and admit of the cylinder G revolving.

The operation of feeding and delivery of the sheets in this press is similar to that of other cylinder presses, and is provided with the usual feed-board t.

I am aware that type-beds have been operated by means of a segment and ropes attached to the ends of the bed and to said segment; and I am also aware that it has been proposed to move the type-bed by means of a single pitman secured at one end to the center of the bed and at the other nd to an arm actuated by a gear-wheel.

In my device there are two pitmen, one end of each secured to eac end of the bed, their other ends secured to the opposite ends of the segment, whereby the movement of said segment insures the certainty of movement of the bed in a direct line with the tracks. The pitmen are not liable to become strained and of unequal length or break,as would cords employed in such connection. The pitmen or springs are kept in place by means of a central flange on the top of the segment. The slotfin the segment and the crank-pin 0, carried by the wheel D and working in said slot, secure the regular movement of the segment and the pitmen carried thereby, so that no undue or irregular strain or jerking can be conveyed to the pitmen or their attached type-bed.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. 1n astop-cylinder printing-press, the combination', with thereciprocating bed B and cylinder 0, of the plate I, having inclined depression h, gear-wheel b, flat spring 1, secured at one end to the face of said gear-wheel, and chuck or pin 70, adapted to pass through an opening in the gear-wheel and engage in the inclined depression h, substantially as and for the purpose set forth.

2. The combination, with the bed B and cylinder C, of the arm I, the pivotal bar 1), spring to, lever q, with its pin 1', the trip 8, and disk m, with its notch or recess in its periphery for holding and releasing the cylinder alternately, substantially as and for the purpose specified.

3. In a stop-cylinder printing-press, the combination of rocker-arm E, having elongated slot f, segment F, having center flange g, springs or pitinen G H, each connected at their lower ends to opposite ends of the segment and extendingacross the same, and connected at their upper ends to the ends of the bed B farthest from the point of connection of their lower ends, gear-wheel D, crank-pin e, and cog-wheel d, as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
